@User: I am unable to build Xyce from source. I am not even able to get past the first stage. I am getting back the error

Trilinos was not built with LOCA support in NOX.
Enable the following in the Trilinos build:
  -D NOX_ENABLE_LOCA=ON

The problem is that I did add

-D NOX_ENABLE_LOCA=ON

to the Trilinos build, and if I look at the configuration file for Trilinos, it seems to indicate that "loca" has been compiled in. So I have no idea what cmake for xyce is complaining about, and since I followed the instructions and got no errors, I have absolutely no idea how to proceed.

That is one freaking long command line. But I'll give it a shot.

@Tim Edwards let me know if the above doesn’t work for you.

I prefer autotools but I didn't see instructions for them in the online documentation. configure + make gets me a lot further, but now I'm getting a halt with the following error:

/bin/ld: //usr/local/lib/libteuchoscore.a(Teuchos_GlobalMPISession.cpp.o): in function `Teuchos::GlobalMPISession::~GlobalMPISession()':
Teuchos_GlobalMPISession.cpp:(.text+0x1b2): undefined reference to `Kokkos::finalize_all()'
/bin/ld: ./.libs/libxyce.a(N_DEV_ReactionNetwork.o): in function `Kokkos::abort(char const*)':
N_DEV_ReactionNetwork.C:(.text._ZN6Kokkos5abortEPKc[_ZN6Kokkos5abortEPKc]+0x14): undefined reference to `Kokkos::Impl::host_abort(char const*)'
collect2: error: ld returned 1 exit status

Any ideas?

Instructions based on the autotools can be found here. https://xyce.sandia.gov/documentation/BuildingGuide.html

Okay. It's likely that the error above has to do with the fact that Matt compiled with MPI and I'm not; I tried to rework the configure options accordingly but probably did something wrong. I'll follow the instructions on the link you posted.

Yes, at the moment we have two different build instructions for parallel and serial.

@Eric Keiter: I continue to have the problem that compilation fails with `undefined reference to

Kokkos::finalize_all()'

. This is being a persistent and unresolvable error. If there is some package I could disable to work around it, I could try that, but otherwise I have no hints as to why the failure occurs. "finalize_all" appears to be defined in /usr/local/lib/libkokkoscore.a. In the xyce Makefile, I don't see any references to kokkos in the XYCELIBS definition, although there are plenty of references to teuchos, nox, etc.

@Tim Edwards Is there any reason you aren't building the parallel version? You can still run with 1 thread...

@Matthew Guthaus: I am building the parallel version (since realizing I was mixing options for the two versions).

Did you install Trilinos with the Kokkos option enabled? Is it properly pointing to the correct Trilinos install (ARCHDIR in my example)?

@Matthew Guthaus: That could be the issue. I'm not sure what ARCHDIR represents, or what it is supposed to point to. I left it out, assuming it would default to the usual install location, which seems to be /usr/local/lib/.

@Tim Edwards The serial and parallel versions need different versions of Trilinos, so they don't just put it in the default location, as far as I understand.

@Matthew Guthaus: Yep, that was the issue. I had to clean out everything and rebuild and reinstal both Trilinos and Xyce from the top, but it worked. Thanks for the help.

Glad this worked out. I was out yesterday so I didn’t see this until today.

@Eric Keiter: Now I just have run-time issues. I'll bug you about those later, though. Have a good holiday weekend meanwhile!
